MOOCs are presented in this article as a fundamental change in the access to education in the world. While not necessarily a completely new invention, the technological context was ripe for them to take off and become established as an important step forward in providing open education for a large number of people. It is argued that MOOCs, if correctly structured and managed, can harness the best of both formal and informal learning, to help students develop their receptive, productive and interactive language competences. It is, therefore, possible to talk about Language MOOCs, or LMOOCs, as a sub-field within MOOC research and practice. Activities that revolve around collaboration and peer review, resting upon basic linguistic notions of the target language, while arguably not as fruitful or enjoyable as direct interaction with native speakers, can still greatly motivate students to experiment with new language and become more proactive than they would in other learning environments. Furthermore, while focussing on the mistakes of other students, they are implicitly reviewing and refining their own comprehension and production. If mobile assisted language learning, or MALL, is talked about as the application of mobile technology to language learning, then given the potential of such technology to increase both the access of students to LMOOCs and also provide them with complementary tools for the courses, we can begin to talk about Mobile Assisted LMOOCs, or MALMOOCs. In this chapter, the nature of LMOOCs is discussed together with the potential role of mobile devices, argued to be the digital equivalent of the Swiss army knife, offering a rich and flexible way of interacting with the real world based upon the array of sensors present and the apps that can be installed on them.
